CLIP FOR FOUNTAIN PENS OR THE LIKE Application filed September Thisimprovement relates more particularly to an improved clip for fountainpens, mechanical pencils and the like, wherein a ball clip is providedfor holding the pen or pencil attached to the pocket or to some otherpart of the clothing.

Clips of this character for fountain pens or the like are usuallysecured to the barrel or barrel cap by means of rivets or other similarmeans, which are more or less unsightly and the clips cannot be readilyattached or replaced.

The object of the present improvement is to provide novel means ofattaching the clip whereby the attaching means is concealed,

thus producing a neat appearing article.

A further object is to provide simple means for attaching the clip,preferably consisting of a screw-threaded member on the end of thebarrel, cooperating with an annular flange or groove for holding theclip in fixed relation to the barrel and the end of the clip incooperative relation with the screw-threaded member, that is the clip isadapted to be 2 held in place by the flange and the clamping efiect ofthe screw-thread-ed member. This construction not only provides anefficient means for securing the clip to the pen or pencil, but providesa ready means permitting the clipto be replaced if it becomes broken ordamaged or if it otherwise becomes necessary to replace the clip.

The preferred form of the improvement r is more particularly shown inthe accompanying drawings, in which Fig. 1 is a side View of the clipattached to a fountain pen barrel cap; Fig. 2- isa front view of theclip and cap as shown in Fig. 1; Fig. 3 is another side view of the clipand barrel cap with the barrel and cap nut and the upper portion of theclip in section; Fig. 4 is a perspective View of the disassembled partsof the clip, barrel and cap nut; Fig. 5 is an end view of the barrel andclip with the cap nut re- 29 1930.

moved and Fig. 6 is abottom or underside view of the cap nut.

Referring to the drawings, it will be seen that the improvement is shownin connection with a fountaln pen barrel or barrel cap A, 5

nut D preferably knurled and of the same di- V ameter as the end of thebarrel, is provided with a central screw-threaded opening E forcooperation with the screw-threaded stud O. In the present instance, theunderside of the cap nut D is formed with a circular recess F producingan annular cylindrical flange G extending about the lower face of thenut, as indicated in Figs. 4 and 6. An arc-portion at H of the fiangeiscut away, the ends of the flange at the cut-out portion being preferablyin radial planes, asindicated at K. i

The clip L may be punched out of sheet metal in the usual way andprovided at its lower end with the usual ball M, which may be integralor otherwise, as desired. The upper end of the clip is bent at N,substantially at right angles to the part L, and is punched or formedwith a semi-circular arouate portion 0, adapted to fit in the recess Fof the cap nut, adjacent the flange G. The portion 0 is preferablyprovided with a hole or cut-out portion at P, which is adapted tocooperate with the screw stud C and fit closely thereabout, while thesemi-circular outer edge of the portion 0 is adapted to fit closely inthe recess F against the flange G.

. Also, it will be seen, particularly from Fig. 5, that the bent-overportion of the clip between the bend N and the semi-circularportion 0isformed wedge-shaped with its edges at R in radial planes correspondingwith the radial lanes or edges K (Fig. 6) of the annular ange G on thecap nut D.

Accordingly the clip is provided with a port-ion extending transverselyofthe end of the barrel and is secured thereto by the screwthreadedmember, the clip being held in place by the annular flange orscrew-threaded stud, and in fixed position by the radially cut-outportion.

- Fromithe above, it vwill be understood that for attaching or removingthe clip, the procedure is comparatively simple. F or attaching theclip, the upper endof the clip 0, P, B is inserted in the recess withedges R in contact with the walls K of the out out portion for retainingthe clip in fixed relation to the barrel.

In a fountain pen or the like, the combination with the barrel, of ascrew-threaded stud extending axially from the end of the barrel, a capnut cooperating with said thread ed stud, an annular flange on said capnut, said flange being provided with a radial opening and a clipprovided with a lateral portion adapted to extend through said radialopening and formed with an arcuate portion cooperating with saidthreaded stud for securing the clip to the barrel when the cap nut isscrewed down. 7

tion 1-1, after which the cap nut D is screwed down on thescrew-threaded stud C, thereby clampingthe upper transverse end of theclip to the end of the barrel between the flange G and thescrew-threaded stud C, substantially as shownin Figs. 1, 2 and 3. Whenit is 'desired to remove the clip, the cap nut D is unscrewed enoughtorelease the clip after which it may be readily removed and replacedwith another clip or left off entirely if noclip is needed. 7

While the flange G and recess F are shown on the 'cap nut, it will beunderstood as a mere reversal to place them on the upper end of thebarrelan'd while the opening in the flange is provided with wedge-shapedor radial edges for providing a wedging effect in holding the clipinposition, this opening may have parallel edges or be form'ed otherwise if desired.

' Furthermore, it-will be understood that various modifications in thedetails of con struction and arrangement of parts may be made withoutdeparting from the spirit and scope of the invention. r
